John Alexander Matthew and Henry Reginald
Neill, Lambeg, Northern Ireland, assignors to
Linen Industry Research Association of the Re
search Institute, Lambeg, Northern Ireland, a
corporation of Great Britain

. 5 Claims.
The invention relates'to- the treatment of tex
tile ?bers "whether associated with non-?brous
tissue or not such as ?ax, hemp, jute, cotton,
wool, arti?cial silk or hair,~and the manufacture
5 of* yarns, threads and fabrics from such ?bers
and to apparatus for canrying out such treat
ment.
'
'
The object of the invention is to impart a crimp
Ol serration to the individual ?bers‘ in a mass
10 of textile ?bers whether associated with non
?brous tissue or not whereby the separation of
, non-?brous tissue may be facilitated and the
properties of ?bers during preparing and spin
ning may be modi?ed to enable the production of
15 yarns, threads and fabrics of a greater diversity
leaving the individual ?bers crimped or serrated
according to the degree of treatment given.
It also further comprises apparatus constructed
with a pair of plain rollers driven to rotate to
gether with a single serrating or crimping blade 5
disposed against and pressed into the nip of the
rollers on the delivery side by a spring or other
suitable means which permits intermittent move
ment of the serrating or crimping blade away
from and back to the rollers.

we are concerned with putting a crimp or serra
tion into individual ?bers crossing the line of
serrations.
The textile ?bers may be treated, whether as
40 sociated with non-?brous tissue or not in a more
or less open or consolidated or partly manufac
tured condition such as bunches of ?ax ?bers,
loose cotton, or wool, in a more or less orderly
form in a layer or sheet, or ?bers in sliver or rib
45 bon form, yarn or thread.
The improved treatment according to the in
vention consists in imparting a serrated e?’ect
to the ?bers. transversely of their longitudinal
axis whereby the ?bers in the mass are so sharply
.50 crimped or serrated that the individual ?bers
in the mass crossing the line of serrations are
themselves sharply serrated or crimped. ,
The invention further comprises a subsequent
mechanical treatment whereby the pleated for
55 mation may be removed from the sliver or rove
B1 (drawn to an exaggerated scale).
In carrying out the invention the serrating or
crimping process may be a preliminary or- inter
mediate stage in manufacture applied to the
?bers:
(a) Before removal of associated non-?brous
tissue such as wood;
~
(b) While in they loose or open state prior to
the preliminary stages of spinning ;i
l
(0) At an intermediate stage while in a sliver
or
rove;
'
v
.
.
(d) After spinning to a yarn or thread.
.The serrations or crimp may be removed from
the mass of ?bers during subsequent processes .
but will be retained .to a greater or less ‘degree.
-in the individual ?bers of the ?nished article.
The serrating or crimping apparatus is con
structed with a pair of plain rollers A A1 be
tween which the ?bers pass with a single serrata
ing 'or crimping blade B or B1 ‘disposed against 55

andpressed into the nip of the rollers on the de
livery side by a spring 0 which permits of a
movement of the blade B to and from the rollers.
The rollers A and A1 may be any of the well
known types of plain rollers used for drawing
?bers of various kinds or mangle-‘or calender
rollers such as a steel under roller and a wood
upper roller, and may be driven by frictional
contact or geared together to rotate in unison.
10 The serrating or crimping blade Bar B1 is mount
ed to permit of adjustment of the pressure against
the. rollers and of the inclination of its axis rel
ative to a line joining the centres of the pair of
rollers.

In the construction shown in Fig. 1 the serrat

drawings, four blades B are shown in action.
The blades B are arranged in rows, and between
each pair of rollers is a guide plateF on which
are ?xed covered conductors I which may be ad
justable as to width, for conducting the material
from one serrating or crimping blade to the next
pair of rollers throughout the machine.
The material is placed on a travelling conveyor

may be either plain or ?uted rollers or a pair of
plane rollers with a serrating or crimping blade

low pressure so that the material is ?attened or 15
rolled but not crimped. This passes to the next
pair of rollers which has the same surface speed,

in front of the drawing rollers, and having
a surface speed greater than the linear velocity of
the pleated ribbon delivered from the said ser

It will be understood that the pleated ribbon
containing the serrated or crimped ?bers can be' 40
treated in any other way by known means, either
mechanical or chemical, without in any way de- "
parting from the scope of this invention.
As applied to loose ?bers, the ?bers are passed _
through the serrating or crimping machine. and 45
are subsequently treated in known manner to
produce sliver, rove or yarn the individual ?bers
retaining more or less of the crimp imparted to
. them.
